The View Menu is a drop down box located on the Control Bar in the Hammer Editor. It contains adjustable settings for the four viewports, offering you a variety of ways to edit your map. The Map Menu is one of the more useful menus in the Control Bar, since it defines how you edit the map, something you'll want to customize for yourself.
